WILLIAM F. CUNNINGHAM, OF BROOKLYN, NEV YORK, ASSIGNOR OF ONE HALF TOENOCH RUTZLER, OF SAME PLACE.

. WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 454,994, dated June 30,1891.

Application filed April 26, 1890. Serial No. 349.581. (No model.)

To all whom, i may concern:

Be it known that I, WILLIAM F. CUNNING- HAM, of Brooklyn, in the count-yof Kings and State of New York, have invented a certain new and usefulImprovement in Weather- Strips, of which the following is a specifica#tion.

My invention relates to an improvement in weather-strips intendedparticularly for outside use between the inasonary or Wall of a buildingand the door or window casing. Experience has shown that it has been amatter of great difficulty to eifectually close the joint between thewall of a stone or brick building and the casing, so as to prevent coldair from creepinglthrough and producing an objectionable draft in theimmediate neighborhood of the window or door casing.

The object of my present invention is to obviate this difficulty and toprovide a cheap and eective weather-strip for such use.

A practical embodiment of my invention is represented in theaccompanying drawings, in whichy Figure l is a transverse section of thestrip, showing the packing located at the angle of the strip. FigA 2represents a partial horizontal section through the Wall ot' a building,window casing and sash, showing the weather-strip in position relativelythereto.

A represents a strip of Wood or other suitable material having two ofits adjacent faces a a formed at right angles to each other, as shown,in order that the strip may be engaged snugly in a corner. It isevident, of course, that if the corner or angle formed by the parts ofthe' structure to which the weather-strip is to be applied were otherthan a right-angled corner or angle the sides d a could be set at acorresponding angle to each other to it such form of angle or corner.The other side a2 of the'strip is here shown of rounded form, and thisis found to be a very convenient and desirable shape, as it makes a neatfinish and is not aexpensive to form, although of course itrnight be ofother desired.

The stripA is provided with a dovetailed groove B, opening at the angleof the strip, and iu said dovetailed groove packing C is inserted andallowed to project out from the mouth of the groove, so` as to becomecoinpressed in the angle or corner when the strip is secured inposition, and thereby eectually close any opening. The packing C shouldbe formed of some suitable iiexible substance, and I have foundthat forthis purpose cotton is particularly well adapted, because it does notbecome hardened by exposure to the atmosphere. groove B will hold thecotton pressed therein securely in position, so that the strip may bemade with its groove already filled with cotton as an article -ofmanufacture and sale upon the market and be cut in lengths to suit thedemands of the purchaser.

In Fig. 2 the wall of the building is represented by D, the Window ordoor casing by E, and the Window-sill by F, the strip A being here shownsnugly fixed in the angle between the casing and wall of the building,with the cotton, which projects nfrom the mouth of the groove, forcedtightly into the angle and effectually stopping any crevices which maythere be formed.

The strip A may be secured in position by nails, screws, or any otherWell-known and suitable fastenings.

What I claim as my invention, and desire to secure by Letters Patent,is-

The herein-described weather-strip, consisting of a body portion A,provided with a dovetailed groove B, opening at the angle formed by twoadjacent sides of the strip, and a packing of cotton secured in thegroove and protruding therefrom at the angle of the strip, substantiallyas set forth.
